To all whom it I I '2 is it kn ws: t a Jess B- ..Mesee a citizen of the United States, residing at Collinsville, thecounty of Madison and State of lllinois, has invented certain new and useful Improvements in Safety Hooks for Carbide Lamps, of which the following is a specification.-

This invention relates to miners carbide lamps, and has particular reference to means used in securing the lamp to a miners cap, so as to hold same in a firm position and prevent dislodgment of the lamp from the cap as is often the case when a minor stoops over.

A further object of my invention is to provide an attachment for miners lamps, which will permit a quick and easy adjustment of the lamp to a plate or holder which is usually attached to the top and peak of a miners cap.

A still further object of this invention is to provide a device of the above stated character, which is simple in construction, efficient for the purpose intended and one that can be manufactured and placed on the market without adding materially to the expense of the lamp itself.

These and like objects of my invention will be better understood as the description proceeds and as is specifically pointed out in the appended claim.

Referring to the accompanying drawing which forms a part of this specification and which clearly illustrates the construction and operation of my improved safety hook attachment,

Figure 1 is a side elevation of a miners lamp attached to a miners cap, with my improved hook, parts of the lamp and cap being broken away.

Figure 2 is a side elevation of a miners lamp showing my improved safety hook attached thereto.

Figure 3 is a perspective View of my improved plate and safety hook holder attached to a miners cap.

Figure 4 is a tranverse section through the plate holder and the safety hook, and

Figure 5 is perspective view of a slightly modified form of safety hook.

Referring to the drawing in detail, like numerals will be used to designate like parts in the different views.

The numeral 1 designates a miners cap provided with a peak 2 of the usual conas a y enyisui able means and o. e Pea- Qt; thesen asat met l Plat 5,- sec nd met p atefi isat aeh dio he from of the metal plate 5 adjacent the point 7 where the plate 5 bends at right angle to the body of same to provide means for'securing same to the top of the cap. The plate 6 is secured to the plate 5 by means of rivets 8. The plate 6 is formed intermediate the edges of same and the entire height to provide a pocket 9 between the inner face of the plate 6 and the outer face of the plate 5, as is clearly indicated in cross section in Fig. 4.

A hook 10, formed of a single piece of wire is attached to the rear of a miners lamp designated by the numeral 11. The wire 10 is bent as at 12 to form arms 13, which are connected as at 14. The arms 12 are compressed when inserted in the pocket 9 and after same are released they have a tendency to move apart which causes them to firmly engage the walls of the pocket, which will make the lamp 4 more secure to the cap and will not permit same to fall to one side or swing sideways when the wearers head'is tilted or turned. The lamp being held securely to the cap.

In Fig. 5, I have shown a slightly modi fied form of hook, wherein a spring clip 15.

is attached to the lamp in place of the wire hook 10.

The spring clip 15 having a large bearing in the cap opening or pocket which will also act to hold the lamp more secure to the cap and prevent the lamp from falling to one side or swinging sideways when the wearers' head is tilted or turned.

In viewlof the foregoing description of my invention taken in connection with the accompanying drawing, it is thought that further explanation as to the operation, construction and objects of same are unnecessary.

While I have shown and described the preferred form of my invention, I realize that various minor changes may be resorted bent angularly in opposite directions coincident to the angle of the top of the crown and the visor of said cap, means securing said ends respectively to the top and visor of said cap to position the body of said plate in a materially spaced relation to the crown of the cap, a second plate having a central transverse channel impressed therein, the side walls of said channel being parallel, means securing said second plate to the outer face of the first mentioned plate so that the upper edge of the former is flush with the upper edge ofthe first plate proper at its junction with the upper angularly bent end and the side edges of the second mentioned plate flush with the side edges of the first mentioned plate, the channel in the second mentioned plate forming a vertical pocket andbearing plate for supporting and'carrying a substantially U-shaped spring wire hook carried by said lamp, said wire hook adapted to be sprung into secure engagement with the aforesaid pocket.

3 In testimony whereof I affix my signature.
